Synovial cavity

Cranial cavity

Pericardial cavity

Verified step by step guidance

Understand the context of the question: A total knee joint replacement involves accessing the knee joint, which is a synovial joint. Synovial joints are surrounded by a synovial cavity, which contains synovial fluid to reduce friction during movement.

Review the anatomical structure of the knee joint: The knee joint is a hinge joint that connects the femur (thigh bone) to the tibia (shin bone). It is enclosed by a synovial membrane and surrounded by the synovial cavity.

Eliminate unrelated cavities: The pleural cavity surrounds the lungs, the cranial cavity houses the brain, and the pericardial cavity surrounds the heart. None of these are related to the knee joint.

Focus on the synovial cavity: The synovial cavity is the smaller body cavity that would be opened during a total knee joint replacement to access the joint and perform the procedure.

Conclude that the synovial cavity is the correct answer, as it is directly associated with the knee joint and its replacement surgery.
